4. Configure the PPP over Ethernet field to enable high speed dial-up connections to the
access point WAN port.
half duplex Select this option to transmit data to and from the access point, but
not at the same time. Using a half duplex transmission, the access
point can send data over its WAN port then immediately receive
data from the same direction in which the data was transmitted.
Like a full-duplex transmission, a half-duplex transmission can
carry data in both directions, just not at the same time.
full duplex Select this option to transmit data to and from the access point at
the same time. Using full duplex, the access point can send data
over its WAN port while receiving data as well.
Enable Use the checkbox to enable Point-to-Point over Ethernet (PPPoE) for
a high-speed connection that supports this protocol. Most DSL
providers are currently using or deploying this protocol.
PPPoE is a data-link protocol for dialup connections. PPPoE allows
a host PC to use a broadband modem (DSL) for access to high-
speed data networks.
Username Specify a username entered when connecting to the ISP. When the
Internet session begins, the ISP authenticates the username.
Password Specify a password entered when connecting to the ISP. When the
Internet session starts, the ISP authenticates the password.
PPPoE State Displays the current connection state of the PPPoE client. When a
PPPoE connection is established, the status displays Connected.
When no PPPoE connection is active, the status displays
Disconnected.
Keep-Alive Select the Keep-Alive checkbox to maintain the WAN connection
indefinitely (no timeout interval). Some ISPs terminate inactive
connections. Enabling Keep-Alive keeps the access point’s WAN
connection active, even when there is no traffic. If the ISP drops the
connection after an idle period, the access point automatically re-
establishes the connection to the ISP. Enabling Keep-Alive mode
disables (grays out) the Idle Time field.
